White paint is the most used paint of all colours. It is the painter's
substitute for light. It is good to start with a base layer of bright
white paint, even if you tone your canvas or wood panel a dark
colour. As paint ages it grows transparent, what is underneath
will show through over time. This white underlayer will keep your
painting bright when this process occurs.
There are 3 basic forms: Lead white, Titanium white, Zinc white.
Lead paint is poisonous, care must be taken during use, it also
dries very fast and any paint mixed with it also dries faster, and is
especially opaque. Titanium does not dry as faster but is still quite
opaque. Zinc dries very slowly and is not as opaque. Zinc is good
for if you are not able to finish the painting in one sitting.
White is the main colour that gives paint its thickness and body, it
is also very durable.
